| Abstract: | Treatment of Os(bpy)(2)Cl(2)] (bpy = 2,2'-bipyridine) with 2-aminoethanethiolate was accompanied by air oxidation to give Os(2-aminoethanesulfinato-N,S)(bpy)(2)](+) (1](+)), which was further oxidized by air to be converted into Os(2-iminoethanesulfinato-N,S)(bpy)(2)](+) (2](+)) under photoirradiation. Complex 2](+) was reverted back to 1](+) by treatment with BH(4)(-). |
